]]>Comment on Parabola, it’s scarily simple… by Elaine Watsonhttps://howardat58.wordpress.com/2017/08/31/parabola-its-scarily-simple/comment-page-1/#comment-606
Thu, 31 Aug 2017 23:42:30 +0000http://howardat58.wordpress.com/?p=3043#comment-606I love that approach! I’ve always taught it using the definition, but putting the vertex at the origin and, for a vertical parabola opening upwards, I would place the vertex on the origin and place the focus on (0,p) and directrix at
y = -p. Then I could place 2 points on the parabola: (2p,p) and (-2p, p) this would give me 3 definite points on the parabola. I would sketch the parabola through the 3 points. I was limited to showing only + and – parabolas that we’re symmetric to the x or y axis.

I look forward to playing around with your approach! I haven’t posted anything on my website for years!

Sun, 30 Apr 2017 10:37:15 +0000http://howardat58.wordpress.com/?p=2769#comment-550It’s not only the angle, it’s the arbitrary (but equal) spacing of the points on the multiplier line as well. I have more to say on this later.

Sun, 30 Apr 2017 02:41:32 +0000http://howardat58.wordpress.com/?p=2769#comment-549The multiplication is a mind-catching one. I wonder how long it takes people to be convinced that the angle of the second line isn’t relevant to how it works.
